[NOTE: ZomBux are a work in progress. Ignore them. Also, the High Score is a little broken. Ignore it, I'm trying to fix it now.] Use the mouse to point your weapon and click to fire. Use the up arrow or W key to move forward. Hold the E key to sprint. Use the R key to reload your weapon. As soon as a Zombie touches you, you lose health. Reach 0 HP, and you lose. :)
